gcode2png

python3 script for 3D rendering gcode files with Mayavi

Features

• --help is showing usage
• different options to show bed, model + moves + supports
• auto adjust camera based on the model dimensions and location
• remove first 5 gcode entries from object - helps not to show pruge lines, which would distract the camera view etc
• option to define output image resolution
• option to show image preview (no more weird unrendered windows)
• set env var LOGLEVEL=DEBUG to see log flood on stderr
• python 3.10+

Examples

Good examples:

Not so great examples:

Known limitations

• python 3.10+
• tested under Ubuntu 22.04, and nothing else
• no longer compatible with forked projects
• some gcode files are rendered weird, see test_nano.gcode, for example I have some custom gcode to trigger photos for timelapse, and thus some renders contain those lines that go to the back of the plate and then to the right - this is especially visible in skullbowl, crystal and test_nano examples
• no support for bgcode
• no support for absolute moves in gcode

Requirements

Tested under Ubuntu 22.04

suto apt install -y mayavi
pip3 install -r requirements.txt

Usage

python ./gcode2png.py --help

python ./gcode2png.py --moves=true --show=true --drop=0 tests/test.gcode
python ./gcode2png.py --moves=true --drop=0 tests/test.gcode tests/test.png

Develop

make clean
make -j12 all
make -j12 previews previews_md

Thanks

• initial gcode2png idea forked from Zst, which was forked from shodushi
• gcodeParser.py

Todo

• add thumbnail generations for Linux
• add install to makefile
